Recent indications from U.S. carriers AT&T ( T) and Verizon ( VZ) haven't been good. Verizon said last week it activated 3.2 million iPhones during the quarter, down from 4.2 million in the Christmas quarter. AT&T said today it activated 4.3 million iPhones during its first quarter, down from 7.6 million in the previous three-month period.

These concerns, along with comments made by Apple supplier Qualcomm ( QCOM) last week about supply issues, have led some analysts to cut iPhone sales estimates. Jefferies analyst Peter Misek lowered his estimate to 28 million to 30 million units this quarter, below his original 32 million.

The iPhone accounted for nearly 53% of Apple's revenue last quarter, so it's clearly a major worry for investors if iPhone sales slow.
